UNITED STATES PATENT OFErcE.

ALEXANDER G. IVILKINS, OF MEADVILLE, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO-ANDY L. DUNBAR, OF SAME PLACE.

BUTTON-SETTING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 367,016, dated July 19, 1887.

Application filed September 3, 1886. Serial No. 212,606.

To all whom it may concern.-

Be it known that I, ALEXANDER G. WIL- KINS, of Meadville, Crawford county, Pennsylvania, have invented certain Improvements in Button-Fastening Machines; and I hereby declare the following to be a full, clear, and

exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a front elevation of myimproved machine. Fig. 2 is a side elevation, partially in section. Fig. 3 is a vertical cross-section of the lower jaw. Fig. 4 is a plan of the lower face of the upper jaw. Fig. 5 is an end 1 view of a removable magazine to contain buttons and supply the buttonconductor. Fig.

6 is a plan of the upper face of the-lower jaw.

Fig. 7 is a plan of the plate on which the magazine rests. Figs. 8 and 9 are details to be referred to.

Myinvention relates to machines for attaching buttons to fabrics by means of staples, and has for its object to provide a hand or power machine for quickly and certainly securing the buttons, all of which will be here inafter fully described, and specifically set out in the claims.

In order that those skilled in the art may make and use my invention, I will proceed to describe the manner in which I have carried it out.

In the drawings there is used for illustration a machine having one fixed and one movable jaw, though both jaws may be movable without departing from the spirit of my lnven-tion. A movable jaw, B, is pivoted at O to a fixed jaw, A, the fixed jaw carrying the button and staple conductor and the movable jaw carrying the devices for upsetting the staples.

0 The button and staple feeding device properis a reciprocating bar, D, which heats up and down on a bolt, D, secured at a in the extreme point of the upper jaw. To the front of bar Dis secured a button-feeding plate, D,

having a slot, a, to receive the button-eyes, and connecting with a transverse slot, a, (see Fig. 4,) in which rest the staples as they pass to the fastening-point. On the front of plate D is secured a spring escapement-detent, I), turning on a pivot, b, and held in positlon by (No model.)

point of the head or stationary jaw of the machine is centrally bored, as seen at d, to receive the shank ofa sliding upsetting-bolt, E, provided with a coiled spring, E, around the 6 projecting end of the shank, to keep said bolt E normally withdrawn to the position seen in Fig. 1. The head 6 of this bolt protrudes into a wide slot, 6, cut vertically in the lower end of bar D, and the bolt is provided at c with a diagonal face resting against a diagonal face,

6', on the bar D, which faces, abutting against each other, act as cams to retract spring Eand throw the head 6 forward in the line of the feed of the button-eyes as bar D is forced upward, in a manner hereinafter described. I1nmediately below a point in line with bolt E the button-feeding plate D is provided on its face with a light spring-detent, f, designed to arrest and hold the button and staple just released by the escapement-detent b.

The movablejaw B has at its end a sliding yoke, F, (see Figs. 1 and 3,) whose sides clasp the sides of the jaw and move in milled or planed ways it h, and the lower plate, F, of which is bored at 71 to receive a headed bolt,

G, secured rigidly to and projecting downwardly from the jaw B. A coiled spring surrounds bolt G, and one end of it bears against the head of the bolt,while the other end bears against plate F, so that the yoke F is non rnally maintained by a spring-pressure in the position shown in Fig. 1. Pivoted in the heads of the yoke F at g are two jaws, H H, having depending tongues g 9, whose inside 5 lines are straight and parallel and have a light bearing against the ends of a transverse stud, h, which passes through the upsetting anvil I, which is screwed into the upper face of jaw B, centrally within the yoke F. The

anvil I is rectangular in cross-section,and two sides of it lie close to two pins, ii, passing across the yoke F and connecting its two sides. These pins hug the square sides of the rigid anvil I and serve as bearings to steady yoke F in its reciprocation back and forth on bolt G. In the inside lines of the sides of yoke F, in a line with the upper meeting line of jaws H H,are cut half-funnel-shaped openings, and adjacent thereto in the meeting edges of jaws H H are half-funnel-shaped openings, and together these make up the funnel-shaped openings 7c 70, which pitch toward the central line, the distance between the openings being substantially the distance between the points of the legs of the staples J, so that as the points of the legs of the staples approach the holes 7c the tendency is to direct each leg centrally to an inwardly-beveled deflecting-surface and give them a preliminary upsetting, as seen in in Figs. 3 and 7.

To provide for a continuous supply of buttons and inserted staples, I have made a rotary magazine, M, having circumferentially arranged a series of longitudinal pockets, 1, designed to be brought consecutively in line with the feeding-plate D". This is accomplished by mounting the magazine on apivot, m, supported by a bracket, 41, secured to the face of the head. The supporting-face of this bracket (seen in Fig.5) is provided with a slot, which registers with slot a a, and each one of the receptacles or pockets is of a contigu-' ration to coincide with slots to a also,-and grooves or recesses 0.0, to guide the bight of thebutton-eyes. g

The operation is as follows: The staples are strung into the eyes of the buttons and the button-carrier is filled withthem, one above the other, and the magazine is set upon the bracket after being filled with buttons and staples, while the buttons and staples are prevented from escaping through the buttonmagazine by the split ring N,which surrounds it and ishinged to a lug, 2i, and is to be with drawn as the pivot m enters the bracket 12. In this position the lowermost button rests against the escapement-detent b. The jaws are brought together, and as sliding bar D is forced upward the projecting end of the detent b is relieved from the stop 12, and the spring I) throws the inner end upward, so that a button may drop in the depression therein contained. The jaws are caused to recede, and as stop 12 again strikes the outer end of the detent it changes its position, making the inner depression drop the contained button and arrest the superincumbent line of buttons. The released button falls along through slota until arrested by spring-detent f, where it remains ready for attachment. The fabric .is inserted between the jaws and the jaws brought together. The pressure upward of the yoke, sustained by the spring around bolt G, forces bar D upward, and as it moves, the cam-faces e and e, coming incontact, throw forward the bolt E until its end, bifurcated slightly atp to straddle the bight of the button-eye,- liesimmediately over the staple in the button held by detent f. The pressure continuing and the bar D and plate D still receding, the end of bolt E presses so upon the staple held by detent f that the spring is overcome and the points of the staple drop against the fabric, through which they are forced, and into the primary deflecting holes 70 k, which start the legs across each other, as seen in Fig. 3. time the pressure is such as to overcome the spring around bolt G, and yoke F begins to descend past the head of anvil I. When the yoke has so far descended that the ends of stud h pass the pivotal points gg of jaws H, the ends of said stud cease bearing on the parallel faces of the jaws and the end of the anvil throws the upper curved ends of the jaws apartand the partially-upset staple is pinched At about this and the fastening completed between the anvil I and the bolt E, making with the fastening staple shown and described in United States Patent No. 345,562, issued to me July 13, A. D. 1886, a most desirable and secure fastening for buttons to all kinds of fabrics.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

1.- In a button-setting instrument, the com- .bination, with an upper jaw, a reciprocating button and staple carrier secured thereto, and

a sliding bolt mounted in said jaw and adapted to move in a line at right angles to the move ment of the button and staplecarrier, of an upsetting-anvil secured to the lower jaw of the machine and adapted to clinch the staples, substantially as set forth.
